The master’s thesis is focused on creating a thermodynamic model of the diesel engine for heavy commercial vehicle. After the model was created, new intake and exhaust pipes are designed based on simulations. Those proposed pipes variants are compared with the series design. After evaluating individual variants, the final version of the new pipes is selected and 3D model for this version is created.

Diploma thesis deals with the design of a condensing steam turbine with one controlled steam extraction. Its working range is 0 to 10 t/h. The first part contains the design of the heat balance scheme. The turbine has two unregulated steam extractions for low-pressure feedwater heater and outlet steam is cooled by water condenser. The main part is the design of the turbine flow channel with one regulative stage using impulse blading and 26 regular stages using reaction blading. The turbine rotating speed is 8500 rpm, which is strength suitable even in critical points. The following chapters are describing the design of the compensation piston and bearings. The consumption characteristic of the steam turbine is shown in the last chapter. Drawing of the turbine section is attached to this thesis. Final turbine power is 9259,7 kW and thermodynamic efficiency 85,5 %.

Objective of the master’s thesis is the thermodynamic design of condensing steam turbine for steelworks place on frame. Steam turbine can be operated with one controlled extraction point from 0t/h to 115 t/h at terminal power 60 MWe and speed of 3 000 per minute. The entered parameters are the admission states of steam at the inlet to the steam turbine, required properties of steam in the process extraction point and temperature of cooling water with flow in water cooled condenser. At the beginning of design of the steam turbine is thermal scheme, defining state of steam in significant places and predetermined mass flow through condensing steam turbine. The following is the design of two regulatory stages with equal pressure blades. First is for High pressure stepped section and the second is for low pressure stepped section. The solution of stepped section is divided into two chapters. The first deals with preliminary determination of the geometry and the number of stages, the second is main part of the whole thermodynamics design of a condensing steam turbine. Stepped section is solved with over pressure blading set on the drum rotor. The calculation is divided into low pressure stepped section for design mode with zero process extraction point and high pressure stepped section, which is designed for off taking mode. Steam turbine is consisted of 6 cones about 32 stages. Thermodynamics efficiency in off taking mode is 86,1 % and mass flow 71,94 kg/s, in condensing mode 83,4 %, respectively 53,01 kg/s. Part of design is strength check of blades, critical speed check and design of compensating piston with the system of labyrinth glands and bearings. Thesis is supplemented by operating characteristics and longitudinal section of condensing steam turbine.

The Diploma thesis named Steam Turbine 300 MW contains the proposal of the Turboset for the steam section of the gas-steam cycle. There is a calculation of the thermal cycle, and a thermodynamic calculation of the combined high pressure - as well as intermediate pressure and low pressure parts. Strength calculation of particular parts and a check of the critical turbine speed follow on from this. This thesis includes a drawing of the cross-section of HP-IP and partial operations. My thesis has been commissioned by Doosan Škoda Power.

This diploma thesis aims to thermodynamic calculation, carbon ring seal calculation and integrated gearbox calculation of single stage mechanicl drive steam turbine. The theoretical part of this work presents general classification of steam turbines, mechanicl drive steam turbine, types of blading and design of turbine seals. In the second part, we further discuss difference between carbon and labyrinth packing.

The aim of this diploma thesis is the design of a condensing steam turbine to drive a pump with a mechanical power of 9 MW. Based on the parameters, a thermodynamic design of the flow channel is performed, including the strength control of the blades, taking into account the API 612 standard. To compensate for the forces arising during operation, a thrust bearing and radial bearings are designed. At the end of the computational part of work, the operational characteristics of the turbine are performed. The appendix contains an idea drawing, which shows a section of the turbine.

In this master’s thesis, a preliminary thermodynamic calculation of the turbine is made. Then, the design and location of the vacuum breaker is devised for this turbine. The aim of the master’s thesis is to calculate a time needed to break the vacuum, ie to determine how long it takes to reach the atmospheric pressure inside the turbine and add-on devices. To verify and improve the accuracy of the calculation there are data measured on real projects used.
